By adjustment of wedges, bring the bedplate to an approximate level and provide the proper dis-
tance above the foundation for grouting 10.05mm to 38.1mm | 3/4" to 1-1/2". Level or plumb the
suction and discharge flanges. Bring pump and motor shafts into reasonable alignment making ab-
solutely certain that motor shaft is not above pump shaft or if it is, that there is a sufficient thickness
of shims under the motor feet to allow for adjustment during alignment.
6.
Tighten foundation bolts, but only finger tight. Maintain the level of the bedplate.
NOTICE:
Final tightening is done after pump is grouted and grout has set at least 48 hours.
7.
Build wood dam around foundation as shown in
Figure 10: Concrete Foundation on page 18
, and
thoroughly wet top surface of foundation. Pour grout in hole provided. in top of bedplate. Use of
non-shrink grout is recommended. Grout should be thin enough to flow out under the bedplate but
not so wet that sand and cement will separate. Grout should be puddled continuously as it is poured
to expel the air and completely fill the space under the bedplate to the level of the grout hole. Strike
along top of dam with trowel to give a neat finished appearance. Allow grout to harden at least 48
hours.
8.
Tighten foundation bolts.
9.
Tighten pump hold-down bolts.
